NGX CTD only with FSUIPC being used! Why?

I'm having a strange problem that just started yesterday. I downloaded the new PMDG NGX the day it was released and had ZERO problems for almost 2 weeks. Last night, i started FSX and every time i loaded the NGX i would get a CTD (crash to desktop) I thought long and hard what had changed, I did assign some buttons a couple of days ago but it worked after that ok. So i removed the Modules folder from FSX and re-started FSX. Now the PMDG NGX loads and works fine!? If I put the module folder, ie; FSUIPC back in the FSX folder, it causes a crash of FSX to the desktop. The error says it's in the NGX.dll so why does or why is something in FSUIPC causing this that didn't the first 2 weeks I had the NGX using it fine with FSUIPC? I am using FSX SP2 with acceleration FSUIPC vs 4.726PMDG NGX w/ hotfix 3 I'm at a loss where to even begin troubleshooting this issue. Thanks for ideasRob
